The radiological appearances of the oesophagus after sclerotherapy for varices.

Fifteen patients, whose oesophageal varices had been obliterated by injection sclerotherapy, were examined by double-contrast barium swallow. In nine patients (60%) the oesophagram was abnormal and demonstrated sharp-edged, longitudinal tramline filling defects and an irregular, patchy nodularity with loss of the normal longitudinal folds. These appearances represent redundant epithelial folds, epithelial tags and healed ulcers produced by endoscopic sclerotherapy.
